Hardie hole

A Hardie hole is a small, precise hole drilled into fiber cement siding or paneling, typically used to accommodate fasteners like nails or screws. Its purpose is to prevent cracking or splitting of the material by controlling stress around the fastener points. By creating these pre-installed holes, installers can securely attach siding while maintaining the material's integrity and durability over time. This technique ensures the siding remains stable and resists damage from temperature changes or movement in the building’s structure.
